Upgrading eclipse on Ubuntu

After totally borking my eclipse install I seriously suggest just removing every mention of the damned thing before installing the new version. By removing I mean move to a new dir in /tmp/ of course.

Things to look out for:

/home/user/.eclipse
/home/user/.mozilla/eclipse
/foo/bar/eclipse

Seriously this should be a lot easier. Anyway - the other thing to attempt is exporting your old software update sites list and then importing this into the new install. This should save an ungodly amount of time reinstalling plugins - which vastly outweighs the amount of time installing takes.

Adding docs to external jars in eclipse

If you have some external jars, like in my case the GWT libraries and you want to add the handy javadoc to them - its not exactly obvious. You need to navigate on the Package explorer view to the "Referenced Libraries". Unfold this tree, and then right click on the relevant library. Click on properties and then javadoc. Add the directory and click validate just to check. Bingo - now the javadoc will appear using the tooltip in the main editor.
